Step 2: Meet Sparkle!

Sparkle is a new blink and bling board from Aniomagic.
Connect to a 3V power source and the surface mount LED on the Sparkle board will blink and bling.
Connect LEDs to the Sparkle board and they too will blink and bling.
It has three different blink patterns programed into the board. Depending upon how you sew the LED sequins to the board you will have a different blink pattern.

Step 3: Design your circuit

Please note: The positive and negative traces should never ever ever touch.

Step 4: Sew the positive and negative traces

On the outside of the skirt following the hemline machine sew a zig zag stitch over the 6 ply conductive thread.
One positive trace.
One negative trace.
Sew parallel lines close enough to connect your LED sequins but, do not let the two traces touch or overlap.

Using a multimeter test for short circuits and resistance.

Once you are confident that the traces are sewn in the correct locations and have passed the multimeter test use the satin stitch sew over the conductive thread again. This is not necessary however it serves as a decorative element as well as protecting the conductive thread from the elements and possible sort circuits.

For a while I have been wondering how to either hide or integrate the conductive thread, or just use old-fashioned colored wire instead and hide it in plain sight.

I think the idea to cover it beneath stitches from a sewing machine is excellent, and as a father of a girl I will most likely put it into practice within the next couple of years when over the counter fairy/angel-wings has top upgraded.

I've been working on a similar project, but I bought pre-wired LEDs..18 on ultra thin wire...from Amazon.com. They have an always on, blinking and a running pattern at the click of a switch and come in a bunch of different colors. It takes a couple of "AA" batteries.

By buying prewired, all I have to do is sew them onto my skirt! (yeah, i'm lazy, but if you're looking for a shortcut...)

Yup! The lights are available at http://www.amazon.com/gp/product/B001W0YZ1Mand I'll try to post a pic when the project is done. I just finished a little el wire decoration on the bodice. The blinky LEDs go on next!

I tried the link, and I guess the don't have them any more ( sigh) so I'm going to go with aniomagic. I hope to combine sparkles with polymer clay to make jewelry. I asked the folks there if I could bake them into PC & they say yes, and if it works, I guess I'll have to do an instructable ( gulp!)
